hi guys, can't figure this one out. I am printing documents (invoices etc) both excel and pdf (i think wordmight be ok) that print some text clearly and some not, i mean on the same page!!! usually anything inside a text box is shaddow/double printing letters partially overlapping. I aligned the heads, no difference. i changed the cartridge and aligned the heads, no difference. uninstalled the printer and reinstalled, no difference. looked for update drivers, no difference. it doesn't matter which tablet/ophone/pc or laptop i print from, it blurs some text whilst other text is as it should be. thoughts? just tried exceland the lines are zig-zagging down the page too. I might add that there was a paper jam that was quite a challenge to remove,umtil i found the roller mechanism can be moved manually. Problem since then.
